Hi,
Will a fix/this fix be part of the 6.2 Release? We will be relying
heavily on fbsd6.2 and pe1950 and are worried about the BCE
stability?
Kind regards,
Fredrik Widlund

Do the following, then retry your test:
ifconfig bce0 -txcsum
Oh, this way it looks much better, thanks. Directory listing
was fine, and copying files during 2-3 minutes over NFS worked
as well. More tests will follow tomorrow.
Next step? :-) Should I put that command somewhere in my init
scripts, or even directly in rc.conf, or wait for a new
if_bce0.c version? I am available for any other PE1950-related
tests if this may help.

Change /sys/dev/bce/if_bcereg.h so that BCE_IF_HWASSIST is
defined to 0. Then recompile.

I know I've brought this up before, but I have a PE1950 with a pair of
bce nics that get pounded on 24/7. I've been using 6.1-R with the
0.9.6 version of the bce driver for a couple of months now. The
driver is available here: http://yogurt.org/FreeBSD/if_bce.c I've
emailed the author of the driver and I've at least mentioned it to
Scott once but I really can't understand why we don't just import
this driver into the tree.
What you just posted is exactly what committed to CVS for 7-CURRENT
and 6-STABLE, and what was proven to break down under moderate to heavy
UDP traffic. I don't doubt that your servers have a load that doesn't
trigger the problem, but if you're curious I can send you a couple of
very simple test cases that will cause your driver to panic and your
network interface to wedge.
